Free Idea: Consumer Reports for EULAs
My idea, which I'd like you to steal- is to make a Consumer Reports for EULAs. MOST EULAs come from pretty similar boilerplate that can be summarized into what you can and can't do with the software.
You'd just need your customer's admin account to specify what he does NOT want employees to agree to (by selecting icons depicting what they want him to agree to), and use that blacklist combined with your maintained list of software EULAs and the associated agreements to decide whether or not employees should accept EULAs. You would also record that an employee has accepted an EULA, and you would also review EULAs that aren't in your system within 24 hours.
Edit: I'm pretty sure my company would pay 5/user/month for this. (around $300/month)
